bpo-46542: test_lib2to3 uses support.infinite_recursion() (GH-31035)
* bpo-46542: test_lib2to3 uses support.infinite_recursion()
Fix a Python crash in test_lib2to3 when using Python built in debug
mode: limit the recursion limit.
The test_all_project_files() test of test_lib2to3 now uses the
test.support.infinite_recursion() context manager when processing the
infinite_recursion.py file to prevent a crash when Python is built in
debug mode.
The two test_all_project_files() tests now use subTest() and log the
refactored/parsed filename (if test_lib2to3 is run in verbose mode).
* Update Lib/lib2to3/tests/data/infinite_recursion.py
